Hello, welcome to the forum. I'm currently using the FX6300, ASUS M5A97 R2.0, GSkill 8x2 1600MHz CL9 kit in blue. My setup includes a Xigmatek 500W non-plus cooler and a Cooler Master T4 tower cooler. The thermal paste I have has been there for about a year.

I've been running at 4.2 GHz with auto voltage and 1866 MHz CL10 RAM OC for five years. However, new online games are causing my CPU to overheat. I can't change platforms because of financial issues.

My issue is that when I try to apply voltages like 1.4V at 4.5GHz, it works fine in Prime95, but if I play games, the CPU overheats and shuts down at around 80 degrees. I have 8CM fans on the case cover, 14CM on the top, 12CM in the back, and 12CM in the front.

What should I do? Some people mentioned the quality of silicone isn't great, but I don't think it will significantly affect this situation.

4.2 to 4.5 is causing the system to overheat, preventing the task and resulting in minimal progress on the outdated processor increasing by 0.3, which isn't worth it.

I tested it for a week without knowing it wasn't reliable. It performed slightly better than before. The graphics card I have is a GTX 960 with 2GB of RAM.

Good Morning
Based on the information you provided, I'm assuming you're using the standard cooler. If that's the case, swapping it for a model like this one from Amazon would be a great first step.

The Hyper T4 from Cooler Master offers budget-friendly cooling with strong performance on current systems, thanks to its four uniquely designed direct touch heatpipes. Its 120mm PWM fan provides a broad speed range and can be adjusted for optimal airflow and temperature control...

Check your bios for options to enhance the tubo boost. On my wife's older FX 6300 using a Gigabyte 970 SLI gaming rig, I increased the tubo boost with minimal additional voltage.

Without investing any cost, you remain largely limited by an outdated and slow processor.
It’s possible your motherboard’s VRM is overheating, which is a typical issue with cheaper FX motherboards.
Consider removing the case cover and using a fan to cool the internal components. This might provide some relief.

No, that's not working. I also tried adjusting the offset voltage. My motherboard isn't fully bare—it has VRM coolers. (You can look up the model on Google.) Each year, I give up because sometimes it just doesn't work.
